    The back-end provided with Stager 1.0 Beta is tailored to work with IP flow data like NetFlow and IPFIX.

    Vsound - a Virtual Audio Loopback Cable

    http://www.xenoclast.org/vsound/
    This program allows you to record the output of any standard OSS program (one that uses /dev/dsp for sound) without having to modify or recompile the program.

    One use of vsound is to help convert real audio files to some other format. Since the real audio format is proprietary, and all we have is a player, we can use the vsound to create a wave file like so:

    vsound -f output.wav realplay input.rm

    waitxxfor

    http://www.hennessynet.com/waitfor/
    This utility will wait until a url is available, until a port is being listened to, until an amount of time has passed or until a shell command succeeds. It's very useful when you want to coordinate the startup or shutdown of services. Each item you wish to wait for is specified on the command line as a series of URLs. The program will repeatedly test each one until it 'succeeds' or until the maximum wait time is exceeded.

    Broadband dreams and multicast 'beams' by Vint Cerf
    http://www.zdnet.com.au/news/communications/0,2000061791,39161201,00.htm

    I have been involved with Multicast IP for many years, and have noticed several problems:

    1) When a Multicast IP network has problems, they are harder to track down than unicast IP problems. The technology is more complex, and debugging tools aren't available.

    2) Billing: It is hard to tell if a particular end-user has requested a particular multicast

    Location Independent Networking

    http://www.ja.net/development/network_access/lin.html
    JANET Location Independent Networking (LIN) Trial Service. This is a service where a guest user can authenticate from a visited organisation back to their home organisation. The visited organisation trusts the home organisation in its response to the authentication process so that if successful, the visited organisation will grant the guest user network access in accordance with its local site policy.

    Uses a hierachy of proxy RADIUS servers - organisational / national / continent.

    http://www.ja.net/development/network_access/JANET-LIN-Architecture-document-Final.pdf

    Initially, wired, web-based redirection, 802.1X and Roamnode network access methods will be supported as part of the trial service.
